Singapore Airlines baggage allowances vary by route and cabin; the table below shows the general standard (always confirm against the official rules and your ticket conditions):
Excess baggage is most expensive at the airport — pre-purchasing online typically saves 30-50%. Power banks and lithium batteries must go in carry-on, never checked.
Special items: golf bags, skis and bicycles usually need advance notice and may carry separate fees; instruments can travel on a purchased seat or as oversize; strollers are generally free to the gate. Liquids in carry-on: max 100ml per container, 1L total.
Lost or damaged? File a PIR at the baggage service desk before leaving the hall and keep your boarding pass and bag tags — late reports make claims much harder.
